14 in a 50/50 mix 20684kpa
What provides the incendiary effect for the Hellfire?
Zirconium sponge incendiary pellets 218g
Ignite and sustain burning in combustible and ordnance to ensure destruction
What happens when the Hellfire thermal battery cools to 204˚?
Battery power is terminated when solidification of the electrolyte occurs
What type of initiator/detonator does the Electronic Safe & Fire Device (ESAF) component control?
Exploding Foil initiator (EFI), slapped type detonator
Detonation which is physically in line with the warhead explosive charge
How does the AGM 114 ESAF work
Using digital circuitry to control the exploding foil initiator and slapper type detonator which is physically in line with the warhead charge
